Definitions

  • Conventional air compressors typically include a compressor, a motor to drive the compressor and an air and oil cooling system to cool the compressed air and lubricating oil.
  • Conventional air compressors are usually enclosed within a housing.
  • a blower, fan or the like draws air into or pushes air through an opening in the housing. Some of the air which enters the housing is drawn into the compressor for ultimate use and the remaining portion of the air passes through the housing to cool the compressor, the motor, the air and oil cooling system, and other components before being discharged from the housing.
  • FIG. 1 schematically illustrates a conventional compressor system 10 .
  • the compressor system 10 includes a housing 14 having an air intake opening 18 and an air outlet opening 22 .
  • a compressor i.e., airend
  • a motor or drive train operatively connected to the compressor are housed within the housing 14 .
  • a fan 26 is positioned downstream from the airend of the compressor and motor to draw air in through the air intake opening 18 . Some of the air drawn into the housing is compressed in the airend of the compressor and some of the air flows over the compressor and motor to cool the compressor and motor.
  • the fan 26 also pushes the air through a plenum box 30 which is used to distribute the air over an air and oil cooler 34 before pushing the air out of the air outlet opening 22 .
  • a problem with the known compressor system described above is the large amount of noise that emanates from the openings in the housing.
  • the air flowing through the housing to cool the compressor and motor flows, for the most part, in a linear path from the air intake opening in the housing through the air outlet opening in the housing.
  • Noise generated by the compressor and motor is freely emitted through the openings in the housing because there is no significant obstruction or other sound reducing means within the housing to reduce the amount of noise which can be carried out of the housing.
  • a feature of the present invention is to provide a compressor system having a housing which includes separate compartments.
  • a first compartment houses an air and oil cooling system for the compressed air and lubricating oil.
  • a second compartment houses a compressor and motor which generate most of the operating noise of the compressor system.
  • a large portion of air drawn in through an air intake opening of the housing is directed to cool the air and oil cooling system positioned in the first compartment.
  • a smaller portion of air drawn in through the air intake opening of the housing is directed into the second compartment to cool the compressor and motor.
  • the second compartment is substantially closed, except for a first limited opening to allow the required amount of cooling air in and a second limited opening to allow the cooling air to exit.
  • the compressor and motor are substantially isolated from the air intake opening and air outlet opening in the housing, thereby reducing the amount of noise generated by the compressor and motor that would normally emanate out such openings. Limiting the amount of cooling air which flows over the noise generating compressor and motor also reduces the amount of air-born noise which can exit out of the openings of the housing.
  • Another feature of the present invention is to provide a compressor system which regulates the amount of air fed to the compression chamber of a compressor, the amount of air used to cool an air and oil cooling system for the compressed air and lubricating oil, and the amount of air which cools the compressor and motor, all for the purpose of reducing the amount of noise emitted from an air intake opening and an air outlet opening in the housing of the compressor system.
  • the present invention provides in one aspect thereof, an air directing device which receives a stream of air flowing through an air intake opening in the compressor system housing. A portion of air drawn in through the air intake opening of the housing is caused to cool the air and oil cooling system for the compressed air and lubricating oil.
  • Another portion of air drawn in through the air intake opening of the housing is separated into two streams of air by the air directing device.
  • the first separated stream of air is fed to a compression chamber of the compressor.
  • the second separated stream of air is directed through a non-linear path to flow over the compressor and motor to cool the compressor and motor, and then out of the air outlet opening in the housing. Because only a small portion of the air entering the compressor system housing is actually used to cool the compressor and motor, and because the air used to cool the compressor and motor travels in a non-linear path through the compressor housing, the amount of noise generated by the compressor and motor that emanates from the openings in the compressor housing is greatly reduced, as compared to conventional compressor systems.
  • FIG. 1 is a schematic illustration of a conventional compressor system.
  • FIG. 2 is a schematic illustration of a compressor system embodying the present invention.
  • FIG. 3 is a schematic illustration of an air directing device according to one aspect of the present invention.
  • FIG. 4 is a perspective view showing the top, back and right side panels of the compressor system housing according to the present invention.
  • FIG. 5 is a perspective view showing the top, front and right side panels of the compressor system housing according to the present invention.
  • FIG. 6 is a perspective view of the compressor system according to the present invention with the top, back and right side panels shown in FIG. 4 removed.
  • FIG. 7 is a perspective view of the compressor system according to the present invention with the top, front and right side panels shown in FIG. 5 removed.
  • FIG. 8 is a right side plan view of the compressor system of FIGS. 6-7 with the right side panel shown in FIGS. 4-5 removed.
  • FIG. 9 is a front side plan view of the compressor system of FIGS. 6-7 with the front side panel shown in FIG. 5 removed.
  • FIG. 2 schematically illustrates a compressor system 100 embodying the present invention.
  • a feature of the present invention is to provide a compressor system having reduced noise emission during operation.
  • Another feature of the present invention is to provide a compressor system which better utilizes the air drawn into the compressor system for actual use and for cooling purposes.
  • the compressor system 100 includes a housing 104 having an air intake opening 108 , an air outlet opening 112 , a first compartment 116 , and a second compartment 120 .
  • a blower 124 positioned within the first compartment 116 draws air through the air intake opening 108 (shown by arrow 128 ), through the first compartment 116 , and discharges the air out of the air outlet opening 112 (shown by arrows 132 ).
  • a compressor 136 having an airend, and a motor or drive train 140 operatively connected to the compressor are positioned within the second compartment 120 .
  • the second compartment 120 is substantially closed from the atmosphere outside the compressor system 100 , except for a restricted first air inlet opening 144 which communicates with the air intake opening 108 of the housing 104 , and a restricted second air outlet opening 148 which communicates with the blower 124 .
  • the blower 124 draws air through the air inlet opening 144 , through the second compartment 120 , through the air outlet opening 148 (shown by arrow 152 ), and discharges the air out of the air outlet opening 112 of the housing 104 .
  • the air flowing through the second compartment 120 cools the compressor 136 and motor 140 .
  • the boundaries of the second compartment 120 and the non-linear path of the air flow into and out of the second compartment 120 provide a sound barrier for the noise generated by the compressor 136 and motor 140 located within the second compartment 120 .
  • the compressor system 100 schematically illustrated in FIG. 2 could have other configurations, so long as the compressor 136 and motor 140 are isolated or spaced away from the air intake opening 108 and the air outlet opening 112 , and so long as the cooling air which flows over the compressor 136 and motor 140 does not flow in a substantially linear path from the air intake opening 108 through the air outlet opening 112 .
  • the compressor 136 may be any suitable compressor, however, for the purposes of the preferred embodiment, the compressor 136 is an oil-flooded air compressor. As generally known, the oil fed into the compressor 136 must be removed from the stream of compressed air before the compressed air may be used downstream for pneumatic equipment and/or other tools.
  • an air and oil cooler or heat exchanger 156 for the compressed air and lubricating oil is provided.
  • the heat exchanger 156 is positioned within the first compartment 116 adjacent to the air intake opening 108 .
  • the blower 124 draws air through the heat exchanger 156 to cool the compressed air and lubricating oil traveling therethrough.
  • an air plenum box 160 is positioned within the first compartment 116 between the heat exchanger 156 and the blower 124 to distribute the air passing therethrough.
  • the air outlet opening 148 in the second compartment 120 is an aperture in the air plenum box 160 .
  • the blower 124 causes the pressure within the air plenum box 160 to be less than atmospheric pressure. A majority of the air drawn into the housing 104 by the blower 124 flows through the first compartment 116 to cool the heat exchanger 156 , into the low pressure air plenum box 160 , through the blower 124 , and then out of the air outlet opening 112 in the housing 104 .
  • the air inlet opening 144 of the second compartment 120 can be an opening for an air directing device 162 .
  • the air directing device 162 includes a first air flow channel (shown by arrow 164 ) for a first stream of air to be discharged from a first air exit opening 168 into an air inlet opening (not shown) of the compressor 136 , and a second air flow channel (shown by arrow 172 ) for a second stream of air to be discharged from a second air exit opening 176 into the second compartment 120 to cool the compressor 136 and motor 140 .
  • a partition 180 is provided in the flow path 164 to regulate the amount of air flowing through the flow path 164 .
  • the openings 144 , 168 , 176 , and 148 are sized to provide a flow of air through the second compartment 120 to prevent the compressor 136 and motor 140 from overheating, and to ensure that the right amount of air flows into the air inlet opening of the compressor 136 so that the compressor 136 does not starve because of a lack of air.
  • FIGS. 4-9 illustrate a preferred compressor system 200 .
  • the compressor system 200 includes a housing 204 having a top side panel 208 , a back side panel 212 , a front side panel 216 , a right side panel 220 , and a left side panel 224 .
  • An air intake opening 228 is provided in the back side panel 212
  • an air outlet opening 232 is provided in the top side panel 208 .
  • the top 208 , back 212 , front 216 , and right 220 side panels have been removed to show the inner compartments and equipment of the compressor system 200 .
  • the compressor system 200 includes a compressor 236 (FIGS. 7 and 9 ), a motor 240 (FIG. 6) operatively connected to the compressor 236 , a separator tank 244 (FIGS. 6-9) in fluid flow communication with the compressor 236 for separating the compressed air and oil from the air/oil mixture received from the compressor 236 , an air and oil cooler 248 (FIGS. 6 and 8) for cooling the compressed air received from separator tank 244 via hose 252 (FIGS. 6-9) and for cooling the oil received from the separator tank 244 via hose 256 (FIGS. 6 - 9 ), a hose 260 (FIGS.
  • the compressor system 200 further includes an air intake directing device or enclosure 272 (FIG. 6 and see also 162 in FIG. 3) removably mounted within the housing 204 .
  • the air intake enclosure 272 includes an air inlet opening 276 (FIG. 6 and see also 144 in FIG. 3) to receive a stream of air flowing through the air intake opening 228 (FIG. 4) of the housing 204 .
  • the air intake enclosure 272 includes a first air flow channel 164 (FIG. 3) between the air inlet opening 276 and a first air exit opening 168 (FIG. 3 ), and a second air flow channel 172 between the air inlet opening 276 and a second air exit opening 176 (FIG. 3 ).
  • the air intake enclosure 272 is preferably lined with sound absorbing material to reduce the amount of noise which may travel therethrough.
  • a tube or hose 280 (FIGS. 7 and 9, and see also FIG. 3) is connected to the first air exit opening 168 of the air intake enclosure 272 and an air inlet opening 284 (FIG. 7) of the compressor 236 .
  • an air filter 288 (FIGS. 7 and 9) communicates with the tube 280 to filter the air before it enters the compressor 236 .
  • the blower 268 draws air in through the air intake opening 228 of the housing 204 (shown by arrow 292 in FIGS. 6 and 8) to cool the air and oil cooler 248 .
  • the blower 268 draws the air through the air and oil cooler 248 , into the air plenum box 264 , and then blows the air out of the air outlet opening 232 of the housing 204 (shown by arrow 296 in FIGS. 6 and 8 - 9 ).
